Using OpenGL to output graphics in a window as defined below,
i=winio@('%es%ca[Simple OpenGL Example]&')
Am wondering if there is a command, maybe in the "winio@" library, to close the window and revert back to regular coding. I would like to close the window and do regular Fortran i/O but the window stays resident and cannot see the Fortran I/O data. Sid Kraft |

The format code %lw enables you to keep a window open whilst doing other things. The window can be closed by setting an associated integer control to zero. See the help on ClearWin+ for further details.
integer ctrl
iw = winio@("%lw",ctrl)
If this is not the last winio@ call for this window then you must add an ampersand...
iw = winio@("%lw&",ctrl)
To close set...
ctrl = 0 |
